[Olsr-users] IPv6 on OLSR

[FlaNKoUTt Soares]

Hello,

me and my colleague have a MANET running olsrd 0.6.0. It is fully working with IPv4. Now we want to put IPv6 on it. But we are having some problems on knowing how it is done.

We send in append to this e-mail our current olsrd.conf configuration. The output showed in the Console is shown next:

 (spam-protected):/etc/udev/rules.d$ sudo olsrd -ipv6

OLSR encountered multiple problems on startup, which should delay startup by 11 seconds.
As this is quite much time, OLSR will sleep only 5 seconds.

It appears that olsrd can't detect our wlan0 interface and we don't know why because it's fully working. Please look at our config of the commands put in olsrd.conf in the Interface "wlan0" part too.

We will really appreciate an answer to our problem.

Best regards
